15 generations of untrained jocks, couch potatoes show big physiological adaptations

...Results of this large longitudinal study have been coming out generation by generation, and now a group of researchers at the University of California, San Diego have found some surprising results at generation #15 (G15), compared with G7. The G7 untrained rats from the "athletic" line had a greater running...

A probe, not an echo

...heme recognizes a small "sweet spot" of the signal coming from the opposite transducer, and only that transducer, and ignores all other pulses transmitted by neighboring transducers. The transducer is able to distinguish the right signal from the right transducer by using coding that is almost identical to...

Six million Africans face famine because of locusts, drought

...in the form of fertilizer and other inputs for the coming planting season." In some areas of Mauritania, northern Senegal, Mali, Burkina Faso, Niger and Chad, the prices of food, especially millet, have as much as doubled, OCHA said, while the prices for undernourished cattle and other livestock have plumm...

Discovery clarifies role of peptide in biological clock

...ormally synchronized as a well-oiled marching band coming onto the field at half time. Herzog and graduate student, Sara Aton, found that mice lacking the gene that makes VIP or lacking the receptor molecule for VIP suffer from internal de-synchrony. When they recorded the electrical activity of SCN neurons...

Oceans more vulnerable to agricultural runoff than previously thought, study finds

...he same way the Gulf of California is to nutrients coming off the land," Matson said. "Inarguably, the effects of marine nitrogen pollution are becoming extremely widespread and severe as a consequence of the global expansion of industrialized agriculture and the intensification of certain practices," the ...

Researchers find promising cancer-fighting power of synthetic cell-signaling molecule

...n to submit the results to a scientific journal in coming weeks. Enigmols are synthetic analogs of sphingolipids, a group of cell-signaling molecules that help cells decide whether to grow or die via a controlled process called apoptosis. Cancer cells are usually defective in these regulatory pathways, so ...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...d by solar energy. "Elephants have generally been coming to the waterhole between noon and midnight, so all the cooking and major noise in the camp has to be done by 2 p.m.," O'Connell-Rodwell notes. Peering through binoculars, she and Eckert finally spot four male elephants on the horizon. The bulls head...

Revolutionary nanotechnology illuminates brain cells at work

... about the vast complexities of the brain over the coming years, such as the role of glial cells in the process of glutamate removal from the synaptic cleft. It's fascinating to see a tool that we are using in plant biology open new areas in neuroscience." ...

Solutions that reduce death of marine life reeled in by International Smart Gear Competition

...lp marine mammals detect and avoid gillnets before coming into contact with them, as well as allow them to escape unharmed if they still become entangled. To create avoidable, detectable, safer gear, the team tinkered with the chemical properties of the ropes. A group of scientists from the Central Institu...

Glow-in-the-dark zebrafish at UH hold keys to biological clocks

...plement the next steps of this research. Prior to coming to UH in 1994, Cahill was a research assistant professor in the Department of Anatomy and Cell biology at the University of Kansas Medical Center in Kansas City and received his postdoctoral training at Emory University. He received his doctorate in ...

Products containing specific probes for detecting alternative splice forms protected

...Cytokine gene family array will be launched in the coming months. SpliceArrays are manufactured for ExonHit by Agilent Technologies. The granting of this patent solidifies ExonHit's leadership in the field of expression profiling and positions the company as the only partner for the conception or use of ge...

Researchers identify protein crucial for survival of Lyme-disease bacterium

...When the tick is not feeding, and no nutrients are coming in, the bacteria are sort of in a quiescent state, waiting in the tick's midgut, which is equivalent to our digestive system." When blood enters the tick gut, Dr. Norgard said it appears that changes in temperature and acidity signal the bacteria th...

No relief for Pacific Northwest drought

...states are now experiencing will only get worse in coming months, and reach levels that were generally seen during the Dust Bowl of the 1930s," said Ronald Neilson, a bioclimatologist with the U.S. Forest Service and professor of botany at OSU.
